Biography
Pietroni was born in the city of Siena in the Republic of Siena (present-day Italy), and attended a military college in Milan. In 1634 he became an officer in the cavalry corps of the Holy Roman Empire after graduating (at only 14 years old), fighting in the Thirty Years War. For his role in the Battle of Nordlingen he was made the Count of Siena, and a young General of the Holy Roman Army.

In the 1640s, he fought on the Rhine River against the invading armies of Sweden and France. Taking advantage of his Italian heritage, Pietroni was able to purchase a corps of Elmeti lancer mercenaries, and brought them with him to Germany to assist in the repulse of the Protestant armies. He was joined by General Octavius von Ulm, a German Landsknecht mercenary leader. Pietroni's army met the Swedish general Gustav Horn at the Battle of Regensburg-am-Rhine in October 1645, and Pietroni led a valiant cavalry charge. However, his cavalry unit of Elmeti was encircled by heavy infantry and Pietroni was shot in the neck by an arquebusier.
